Thank you guys for helping me and giving some important information! I think I'll let them flower until they finish. And soon will be my next try with good seeds. Yep, I see my mistake and I definitely agree. Next time I hope I'll make it better...

They are all hermied, but has many of hairs (now even brown hairs!).. And, of course, many of balls. But it won't be worse if I let them do their job. And I'll report how it goes.

Thank you!
